Nitrogen, argon recovery, hydrogen recovery

rocess

1. Crude Neon and Helium Production:The first step is to produce crude neon and helium by removing nitrogen from the raw materials and concentrating them. This is done using a low-pressure liquid nitrogen as a cold source in a condenser or auxiliary tower to condense nitrogen in the feed gas, resulting in a crude neon and helium mixture with a neon and helium content of about 1% to 3%.
2. Hydrogen Removal:Some processes require hydrogen removal, which is done using an oxygen-added catalytic method to convert hydrogen into water, which is then adsorbed and cleaned by a dryer.
3. Nitrogen Removal:Nitrogen can be removed by condensation or adsorption using activated carbon at low temperatures.
4. Purification and Separation:The crude neon and helium mixture is further purified and separated into pure neon and helium. This is achieved through a combination of condensation and adsorption methods. The gas is cooled and passed through a rectifying tower, where neon and helium are separated based on their different boiling points.
5. Final Processing:The purified neon and helium are then subjected to multiple stages of cooling, reheating, and buffering to ensure high purity. The neon is gasified and sent out, while the helium is also processed and stored as a gas.

Features

• High Purity:The purification process is designed to achieve high purity levels of neon and helium, making them suitable for various industrial applications.
• Energy Efficiency:The apparatus utilizes multiple stages of heat exchange and cooling, which helps in recycling energy and reducing waste.
• Stability:The process is divided into several steps, each designed to remove specific components, ensuring stability and reliability in the purification process.
• Advanced Adsorption Technology:The use of activated carbon and other adsorbents in the process helps in effectively removing impurities such as nitrogen.

Applications

• Lighting:Neon is widely used in lighting applications, such as neon signs and lamps.
• Cryogenics:Helium is used in cryogenic applications due to its low boiling point and ability to maintain extremely low temperatures.
• Scientific Research:Both neon and helium are used in various scientific experiments and research applications.
• Medical Applications:Helium is used in medical imaging technologies like MRI machines.
